"We've been sourcing DOT brake fittings from Yaochong for over 3 years. Every batch passes our incoming inspection without issues -- zero returns, zero claims. Their lead times are predictable and the pricing is consistently competitive. This is exactly what we need from a long-term supplier."

Michael R.

Procurement Manager · Heavy-Duty Truck Parts Distributor, USA

"I was skeptical switching suppliers, but Yaochong's team walked me through their quality control process step by step. When our first container arrived, the thread accuracy was perfect and all fittings passed our pressure tests. The DDP option saved us a lot of customs headache. Highly recommend."

Sarah L.

Supply Chain Director · Hardware Wholesale Importer, Canada

"We needed custom NPT adapters with tight tolerances for our pneumatic assemblies. Yaochong's engineers reviewed our drawings and suggested a small modification that actually improved sealing. Production quality was excellent and delivery was on time. We've placed four orders since and each one has been consistent."

Engineering Procurement · Pneumatic Equipment Manufacturer, Germany

"What I appreciate most is their spot stock for standard DOT fittings. When I have an urgent order, I can get product shipped within days instead of waiting weeks. Megan and Jack are always responsive -- they treat every order, big or small, with the same professionalism."

James D.

Owner · Truck Accessory Retail & Wholesale, Texas, USA

"We import hydraulic fittings from several Chinese factories. Yaochong stands out because their quality control is genuinely systematic -- not just paperwork. We received full traceability documentation with our last order. The salt spray test results exceeded our requirements. Solid factory, solid team."

Purchasing Director · Industrial Hydraulics Distributor, Brazil

"We needed private-label packaging for our OEM brass fittings range. Yaochong handled everything -- custom box printing, individual poly bags, and part number labeling. The product quality matched our brand standards and the whole process was smooth. Our customers can't tell the difference from premium domestic brands."

FAQ

Frequently Asked Questions

Everything you need to know before placing your first order. Can't find the answer you're looking for? Contact our team directly.

Are your DOT fittings FMVSS 106 certified? What documentation can you provide?

Yes. Our DOT brass fittings are fully certified and comply with FMVSS 106 standards as required by the U.S. Department of Transportation. We can provide DOT certification documents, ISO 9001 certificates, material test reports (H59/H62 copper content), pressure test records (500 psi), and AQL inspection reports for each batch. Custom documentation packages are also available upon request.

What quality control steps do you perform before shipment?

Our quality control is multi-stage and fully documented:

  • Incoming: H59/H62 brass bar stock verified for copper content and batch certificates.
  • In-process: Multi-point sampling with SOP documentation at critical machining stages.
  • Performance: Air tightness test, 500 psi pressure test, thread gauge inspection, salt spray test.
  • Final: AQL sampling inspection before warehousing to prevent non-conforming products from shipping.
Do you support OEM/ODM? Can you produce from our drawings or samples?

Absolutely. Full OEM and ODM capabilities are a core part of our service. You can submit engineering drawings (PDF, DWG, STEP) or physical samples, and our in-house engineers will review them, provide feasibility feedback, and suggest optimizations where applicable. Custom packaging -- including private-label boxes, poly bags, and part number labeling -- is also available. Share your requirements and we'll provide a detailed quotation within 24 hours.

How do you handle quality claims or defective products?

We take after-sales accountability seriously. If you receive non-conforming products, our dedicated sales team will investigate using our full-process traceability system to identify the root cause. Depending on the situation, we offer replacement shipments, credit notes, or refunds. We do not deflect responsibility -- our goal is to resolve issues quickly and protect your business operations. Our repeat order rate above 98% reflects this commitment.

What is your minimum order quantity (MOQ)?

We offer flexible MOQ to accommodate businesses of all sizes. For standard catalog items that we keep in rolling inventory, small mixed batches are welcome -- ideal for testing new SKUs or topping up stock. For custom OEM/ODM orders, MOQ varies by product complexity. Contact our team and we'll work out a solution that fits your procurement volume.

What are your standard lead times? Can you handle urgent orders?

Standard production lead time is 15-25 days depending on order volume and product specifications. For in-stock standard models, we can ship within 3-7 days. We maintain safety stock based on demand forecasting specifically to handle urgent orders without premium pricing. Our factory is located 30 km from Ningbo Port, enabling fast container loading and departure.

What shipping terms do you offer? How do you handle logistics?

We support FOB Ningbo as our standard term, which is ideal for buyers with established freight forwarders. We also offer flexible DDP (Delivered Duty Paid) for customers who prefer a fully managed import experience with no customs surprises. Our factory's proximity to Ningbo Port (30 km) ensures fast container loading. Our foreign trade team proactively tracks shipment progress and provides timely updates throughout transit.
